Pelican shows two brands, one for $9.75, and one for $13. I saw somewhere in this thread someone state that many aftermarket boots are thinner than OEM, and therefore won't last as long, although my left one was replaced by the PO at the dealer about 20,000 miles ago, and it looks like it's already cracked, so maybe OEM is crap, too. Anyway, for another data point, OEMBimmerparts has them for $22.50 per side. Any idea if there is any difference in quality among all these widely varying prices?
